SOLUTION: In the case of high speed traveling, a high-speed motor 23 is rotated at the stoppage of a low-speed motor 10, and thereby a high-speed gear 25, an external gear 15 and an internal gear 14 are all rotated, whereby a planetary gear 20 revolves around a sun gear 12, and then an output shaft 21 is rotated via a carrier 18, then an axle 3 rotates at high speed via an output gear 22 and an axle gear 4, traveling at high speed. In the case where it is stopped at the specified position during low-speed traveling, the low-speed motor 10 is rotated at stoppage of the high-speed motor 23, the sun gear 12 rotates, and the planetary gear 20 revolves on the inside of the internal gear 14, the output shaft 21 rotates via the carrier 18, so that the axle 3 rotates at low speed, stopping it at the specified position upon low-speed traveling.  Accordingly, a speed variable range is enlargeable, and also accurate positioning is thus inexpensively realizable.

Title: Overvoltage/overcurrent protective circuit for current type transistor inverter
Inventor: METSUGI MASATAKE
IPC: H02H7/122
Filed: 1990-11-21
Abstract: PURPOSE:To protect a transistor as a switching element by connecting first and second voltage clampers for clamping overvoltage, respectively, between output terminals and input terminals of a reverse converting circuit and short- circuiting the input terminals when an overcurrent flows therein. CONSTITUTION:Upon occurrence of short circuit on load side, differential voltage between VID and VOD exceeds a threshold VTI at the second and following cycles of output frequency because the time constant of a capacitor and a discharge resistor in a first surge voltage absorber 11 is shorter than that in a second surge voltage absorber 12. Consequently, a short circuit operation commander 13 functions to short-circuit input terminals I1, I2. As a result, a short circuit is established in a reverse conversion circuit 4 which is conventionally provided only with a current path and the forward voltage drop of the short circuit is lower than that of the reverse converting circuit 4 and thereby the most of the current flows through the short circuit 13.
